read() Method
In This Topic
Reads the next byte of data from the input stream. The value byte is returned as an `int` in the range `0` to `255` . If no byte is available because the end of the stream has been reached, the value `-1` is returned. This method blocks until input data is available, the end of the stream is detected, or an exception is thrown.

A subclass must provide an implementation of this method.
